162 GENUS CARIBLATTA (oRTHOPTERa) 



tion dark markings occur dorsad on the vertex and dark blotches 

 break the dorsal facial bands, of which the dorsal is the widest; 

 while in one from San Domingo, a condition somewhat resem- 

 bling the normal type in C. insularis is found. Pronotum with 

 lateral margins transparent with a very weak brownish suffusion; 

 disk buffy washed with saccardo's umber with a very fine pictur- 

 ing of bister.^ ^ Tegmina transparent tinged with brownish, the 

 veins translucent saccardo's umber.'^ The dorsal portions of the 

 insect, as a result, appearing diaphanous but in general shaded 

 with saccardo's umber. Wings transparent, hyaline, moderately 

 iridescent; veins translucent brownish. Abdomen clay color be- 

 low, with a broad medio-longitudinal band and on each side a 

 narrower submarginal band of blackish brown, which bands 

 extend only to the base of the subgenital plate. ^^ Limbs cinna- 

 mon buff, frequently flecked at the bases of the heavier spines 

 with dark brown.

1^ Specimens in the maximum recessive coloration show only traces of these 

 markings. In the series before us every gradation from this condition to the 

 maximum of intensive coloration, in which the picturing is very strongly and 

 sharply defined, is found. In the material from Hayti and Little Cayman 

 Island and numerous specimens from Cuba and Jamaica, distinctly recessive 

 coloration is shown, the maximum of this being found in a few Cuban spec- 

 imens. The series from San Domingo and Porto Rico average rather intensive 

 in coloration. These differences would appear to be due wholly to local 

 environmental conditions. 



18 Occasional individuals have the anal vein of the tegmina slightly suffused 

 with a darker brown, while in a few specimens from Cuba the tegmina have a 

 few microscopic dots, very much smaller but of the same character as those 

 found in C. pundipennis (see p. 174). 



18 In specimens of recessive coloration, the median band is no wider than the 

 submarginal bands; in some females of intensive coloration, the subgenital 

 plate is heavily marked mesad with blackish brown.
